The two clubs will meet over two legs next month to battle it out for a place at Wembley, where promotion to the Championship will be the prize.
Dons and Town are destined to finish fourth and fifth, only which way round remains unclear with two games remaining. The fourth-placed team will play the second leg of the semi-final at home.
With this in mind, Robinson said: "We have two matches left before I will worry about Huddersfield in two weeks' time - and I will worry about them because they are a very good side.
"Huddersfield are difficult to play home or away. We want to finish fourth to better last year's finish, and that would give us the perceived advantage of playing them at home in the second game."
